I have created three materalized view (MV1 MV2 MV3) from different databases into a single database.
Now my requirement is I want a table which include some fields from all my materialized views but insertable.

Sorry for uncomplete requirements.
Actual requirements are as follows.

Materialized Views (MV1, MV2, MV3) these are on commit refresh.
Now I want a single materliazed view (some column from MV1, some from MV2 and some from MV3). But this materliazed view whould be insertable.
